A teacher said something about milk in the dark is healthier than milk in light but I don't remember, do you?

Question

He said something about vitamins being destroyed in the light or ultraviolet radiation, I want to know this because I have to do a project on it as soon as possible, someone please help, thank you very much.

Answer 1

Milk, if exposed to either sunlight or artificial light, can develop flavor changes and nutrient losses, especially of riboflavin (vitamin B2), vitamin A (particularly added vitamin A), vitamin C (which is present in low quantities in milk), and added vitamin D.
The extent of flavor changes and nutrient losses depends on several variables. Among these are the light intensity, illuminance and wavelength, the distance between the light source and milk container, container material, amount exposed surface area, surface to volume ratio, temperature, and duration of exposure
In terms of nutrition, loss of riboflavin is directly related to the amount of ultraviolet light transmitted through the container.
Vitamin C or ascorbic acid is particularly light-sensitive. In milk, the rate of destruction of vitamin C is proportional to the amount of light transmitted through the container.

Answer 2

Refrigerated milk in supermarket cabinets can develop off-flavors and lose nutrients after four minutes of exposure to direct sunlight, and after four hours of exposure to fluorescent display case lighting.

Milk in glass or plastic containers are most vulnerable, but off-flavors will also develop when milk is packaged in paper cartons.

Promolux Safe Spectrum lamps emit lower levels of UV and visible spectrum radiation, thus reducing the rate of damaging chemical reactions in milk and dairy products.

Answer 3

I can't remember what does do it but yes that's why milk companies at least in my state have started making white bottles instead of clear bottles. The light shining on them does something to the milk which makes it not as good for you.

Answer 4

Yes I have heard that milk in clear plastic containers loses some of it's benefits. I heard only buy milk in cardboard containers.

Answer 5

All I've heard is that milk in clear plastic jugs lose more vitamins (from letting more light in) than paper cartons.(they keep more light out).

Answer 6

Vitamin D is easily destroyed by sunlight.

Answer 7

Yes, that's why some come in yellow cartons.
